SHOCK-ABSORBER.

Specification of Letters Patent.

Patented Sept. 25, 19117,

Application filed February 2G, 1917. Serial No. 151,046.

To alb whom t may concern:

Be it known that I, HOWARD G. CARR, a citizen of the United States,residing at 910 East Main street, in the city of I'Ioopeston, in thecounty of Vermilion and State of Illinois, have invented new and usefulImprovements in `Shock-ribsorbers, of which the following is aspecification.

rIhis invention relates to a device that attaches to the shackle of the'ordinary vehicle spring, and gives easy riding qualities to a vehicle.It accomplishes this object by performing in general three functions.One function is to give an automatic spring adjustment to the variousloads the vehicle may carry; another function is to relieve the I attainthese objects by the mechanisml illustrated in the accompanyingdrawings,

in which- Figure 1 shows a side view of the device attached to anautomobile spring suspension; Fig. 2 shows a sectional view from theline 16 in Fig. 1; Fig. 3 shows a sectional view of the same characteras Fig. 2, showing a modification of the device.

Similar characters of reference indicate like parts throughout all theviews of the drawings.

Referring to the drawings, 4l is the vehicle frame, 5 is the vehiclespring, 6 the perch, and 7, 7 the shackles. Secured by the bolts 11, 11to the shackles 7, 7 are the levers 8, 8. Secured to the other ends ofthe levers 8, S are the contractile springs 9, 9, which are suspended bythe yoke 10 from the frame fl.

In Fig. 3 I show a single lever embodiment of my invention. The lever 12is secured to the shackles 7, 7 by the clamp 13 and the bolts 14, 14.The other end of the lever 12 is supported by the contractile spring 15which is suspended from the frame lin any suitable manner.

The levers 8, 8 or 12 may be secured to the shackles 7, 7 in any othersuitable manner.

lVith th-e springs 9, 9 disconnected the shackles 7, 7 would stand inthe position indicated by the dotted lines 18 and the levers 8, 8 wouldstand in the position indicated by the dotted lines 17. llVhen thelevers 8, S are secured by the springs 9, 9 and the yoke 1() to theframe 4, the various members of my device and of the vehicle are in theposition shown in Fig. 1, and the load is carried by the tension of thesprings 9, 9, since raising the ends of the levers 8, 8 will not allowthe tension of spring 5 to be flexed beyond its normal tension until thesprings 9, 9 are extended enough to let the shackles 7, 7 and the ond ofthe spring 5 pass beyond the position shown by the dotted lines 1S, thenthe spring 5 would be extended beyond its normal length and itstensional force would help to supplement the tensional forces of thesprings 9, 9 and assist or relieve the springs 9, 9 when overloaded orcx tended.

The springs 9, 9 and 5 exert tensional forces in opposite directions onthe frame il, consequently the body is not affected by torsionalstresses arising from tensional forces of the springs. The springs 9, 9in retract* ing after extension, pull downwardly on the frame Ll,preventing an upthrow or rebound of the frame and body of the vehicle.

I claim:

In combination with a frame, a spring supporting said frame, a perch,and shackles supporting said spring from said perch, a lever having anend adapted to be attached to or detached from said shackles, the otherend of said lever being secured to a contractile spring, and means forsuspending said contractile spring from said frame.

In testimony that I claim the foregoing as my own, I have hereto aiiixedmy signature in presence of two witnesses.
